Routers are the most unreliable pieces of junk other than Printers. Very few of them last more than a year for me.
I recently tested about 5 of them trying to stream HD reliably to my upstairs TV without much luck. The Belkin one I tried had the best signal and speed but kept having connection issues.
I also had a router once that after every two weeks I'd have to unplug it in order to get it to work.
I actually had a linksys router die once. Nothing I did could fix it.
The worst router I ever had was one with built in VOIP for Vonage.
Right now i'm using a Netgear router. Stupid easy to install. Go to specific IP address once connected and you're done.
BTW I don't know if this is common knowledge but I've heard Wireless-G has better range than Wireless-N.
Don't get me started on ink jet printers....
I use a Brother Laser printer and it's been going non-stop for at least 5 years.
Battery Backups (UPS) are annoying too. I had one take one for the team and it costs $75 to replace it's stupid battery!!
